Gtk.RadioButton.prototype.join_group

function join_group(group_source:Gtk.RadioButton):void {
    // Gjs wrapper for gtk_radio_button_join_group()
}

Joins a Gtk.RadioButton object to the group of another Gtk.RadioButton object

Use this in language bindings instead of the Gtk.RadioButton.prototype.get_group and Gtk.set_group methods

A common way to set up a group of radio buttons is the following: |[ GtkRadioButton *radio_button; GtkRadioButton *last_button;

while (/* more buttons to add */) { radio_button = gtk_radio_button_new (...);

gtk_radio_button_join_group (radio_button, last_button); last_button = radio_button; } ]|
